To a whom, it may concern:

Be it known that i, HENRY Scrmnics, residing in Milwaukee, 1n the county of Mil waukce and State of Wisconsin, have. invent ed new and useful Improvements in Turbine- Engines, oi" which the following is a descrip tion, reference being bad to the accomjntroqing drawings, which are a. cation.

This invention relates to turbinewngincs, and comprises tnrbincrn inc for use with steam or other pressure fluid which will be balanced in the pressure upon its rotating parts, so as to cause no undue end thrust.

This invention also comprises a turbineengine having a plurality oi concentric series or rings of blades or buckets adapted to successively receive the steam or other pressure fluid and be influenced thereby to produce the same tendency upon the rotating mono her, the transfer of pressure fluid from one set of turbine-blades to another being accomplished by means of suitable nozzles.

This invention also comprises a turbinecngmc having blades of novel construction and mounted in a new manner.

lVith the above and other objects in view the invention further consists in the novel do tails of construction a nd arrangement of parts as herein set forth and their equivalents.

Referring to the accompanying drawings, in which lilrc characters of reference lifidlCttG the szune parts in the several views, Fig re 1 is a side elevation, partly in vertical central section, of a turbine-engine cimstructcd in accordance with this invention. 2 is an end elevation of the stationa y portion th V of with the inlct-chainber partly sectioned. and tho nozzleq'mssages showin dotted lines. Fig. 3 is plan view of a portion thereof. Fig. 4. is a sectional iew or one of the nozzles. Fig. 5 a detail view showing several turbine-blmlcs in their relation to each other, and Fig. 6 is a plan view of one of the turbine-blades.

In the drawingsfiil ri' prssents a central stationary body portion of the turbine which is provided with any suitable supportingbase 11 and which has shell-like outercas ings 12 removably secured to its opposite sides. The casings 12 form suitable been ings (not shown) for the rotatabie port of the turbine, which comprises a pair of movable members 13 on opposite sides of the stationary member 10 and connected together through a central opening of said stationary part ofthis specilimember by means of a boss 14: on one movable member threading into a sleeve 15 on the other movable member. Each of the movable members 13 has a shaft 16, which is journeled in the outer casings 12, as before mentioned, and which is provided with a s1. table steam-tight packing 17 of usual construction to prevent the discharge of steam which may accidentally find its way be 0nd the movable members. As the two sic es of the stationary member 10 and the two movable members 13, which actively cooperate therewith ore identical in their construction, ectively, the description will be confined to the construction of one side of said stationary member and the movable member adjacent thereto.

The side of the stationary member 10 and the inner face of the movable member 13 are fitted to each oth r very closely, and at the outer cds es of their meeting faces they are \D provided with S'i-(QEZIPilgllt connections, comprising concentric flanges 18 on the former lit-ting within concentric grooves 19 in the latter. The active face of the movable member 13 is also cut away or recessed beof blades 20. Each blade has an oblong rectangular base 21, with the integral outwardlybent blade portion shorter than the. base and extending at an angle thereto. The blades of the outer set have, their bases 21 fitted into on ennular groove around the outer edge of the cut-away portion of the movable member 13 and a re arranged one after another in the manner shown in Fig. 5, their upstanding inclined blade portions standing flush with the inner face of said movable member and against the outer edge of the cut-away portion. The circular series of blades thus arranged is firmly secured to the movable member 13 by means of a clamping strip or ring 22, which is countersunk within the member and has a shoulder on eacli side to receive the projecting ends of the bases of the blades, said ring standing flush with the outer edges of the blades and a ainst their end edges and being secured to tie member 13 by means of screws 23. Any number of other concentric series of blades may be attached in the same manner, there being three in all, as here shown, the last series fitting wi thin a groove at the inner edge of the cutaway portion of member 13, corresponding in which the first or outer sc- Mk-S Was inserted, and the last two Soto o. lJiJ' EES using olampod by the inner nozzles 25, .loaliling to the opposito iu-tivo hilt faces of tho stationary n1eu1- 2.
